Dirham - Anonymous - citing Abd'Allah b. Tegin Imitating Samanid prototypes

Volga Bulgaria's anonymous imitative dirhams occupy a peculiar niche in early medieval numismatics: they were struck not to deceive, but to satisfy the raw silver demands of a fur-trade economy that ran on weight rather than authority. The citation of Abd'Allah b. Tegin — a Samanid governor of the late 10th century — on an anonymous Bulgarian issue reflects how Islamic calligraphic formulas functioned as commercial signals long after the political figures named within them had died or lost relevance.

The Samanid prototype was the dominant trade coin of the northern fur routes, and Volga Bulgarian mints copied the format because merchants on the Volga-Baltic axis trusted it.
